Abstract: Improvements in graphics processing pipelines are disclosed. The graphics processing pipeline processes graphics objects in a particular order (application programming interface order—“API order”) as requested by an application or other entity. However, certain components within the graphics processing pipeline, such as the pixel shader stage, may process those objects out of order. A technique is provided herein to allow the pixel shader stage to complete and export processed fragments out of order. The technique includes using a scoreboard to determine whether fragments ready to be exported from a pixel shader stage are the newest fragments in API order. If the fragments are the newest in API order, then the fragments are exported. If the fragments are not the newest in API order, then the fragments are discarded.

Abstract: Techniques for performing shader operations are provided. The techniques include, performing pixel shading at a shading rate defined by pixel shader variable rate shading (“VRS”) data, and updating the pixel VRS data that indicates one or more shading rates for one or more tiles based on whether the tiles of the one or more tiles include triangle edges or do not include triangle edges, to generate updated VRS data.

Abstract: Techniques for processing pixel data are provided. The techniques include, in a first mode in which blending is enabled, reading in render target color data from a memory system; blending the render target color data with one or more fragments received from a pixel shader stage to generate blended color data; outputting the blended color data to the memory system utilizing a first amount of bandwidth; in a second mode in which blending is disabled and variable rate shading is enabled, amplifying shaded coarse fragments received from the pixel shader stage to generate fine fragments; and outputting the fine fragments to the memory system utilizing a second amount of bandwidth that is higher than the first amount of bandwidth.

Abstract: A method and apparatus for processing color data includes storing fragment pointer and color data together in a color buffer. A delta color compression (DCC) key indicating the color data to fetch for processing is stored, and the fragment pointer and color data is fetched based upon the read DCC key for decompression.

Abstract: A method and apparatus for integrating data compression in a computer system includes receiving first data at a first system level. Based upon a number of planes of the first data being less than or equal to a threshold, the data is compressed with a first data compression scheme, and transferred to a second system level for processing. Based upon the number of planes of the first data exceeding the threshold, the first data is transferred uncompressed to the second system level for processing. Based upon the received data at the second system level being compressed with the first compression scheme, the data is transferred to a third system level, and based upon the received data at the second system level being uncompressed with the first compression scheme, compressing the data with a second compression scheme, and transferring the compressed data to the third system level.
